Śrī Vyāsadeva was advised by Nārada to describe the science of God directly by relating His transcendental activities. Vyāsadeva is himself a personality expert in this science, and he is unattached to material enjoyment. Therefore he is the right person to describe it, and Śukadeva Gosvāmī, the son of Vyāsadeva, is the right person to receive it.
